WINDOW CONSTRUCTION.

Specification of Letters Patent.

Patented Jan. 17, 1922.

Application filedI October 30, 1920. Serial No. 420,655.

To (all @Uh-0m t may concern:

Be it known that I`r PHILIP BoLouH, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and' Improved lVindow Construction, of which the following is a full, clear, and exact description.

This invention relates to a window construction. and has for an Object to provide a window construction which provides a' rigid, compact and efficient window which at all times is waterproof.

Another object residesin the provision of means whereby a pivoted window throughout itsentire movement is so constructed as to prevent a` leakage of water through the joints of the window;

A further object resides in the provision of theparticular construction and arrangement of parts hereinafter described and claimed and shown in the accompanying drawings. Y

In general my invention comprises a weatherproof structure for windows, with particular reference to windows which are used in series and are pivoted where the ends of adjacent windows overlap each other. It hasbeen found exceedingly difficult to construct windows of this sort that are absolutely waterproof, particularly around the portion of the window where it is pivoted to a stationary beam or stud. I overcome this difficulty by the invention which forms the subject matter of this application in that in any position in which the window may be disposed the joint, particularly around the pivot point, is always watertight, andwhen the window is closed the entire structure is waterproof.

The invention is shown in the drawings, of which- Figure l is a partial elevation of a series of pivoted, overlapping windows, showing them in their closed position; Y

Figure 2 is a. section taken on the line 2 2 of Figure l;

Figure Bis a side view showing one of the windows open; y

Figure 4: is a section taken on theline 4-4 of Figure 1; and

Figure 5 is a section'talen on the line 5 5 of Figure 1. Y

Windows constructed in accordance with vertical or vertically inclined series of overlapping, pivot-ed windows, such as are adapted for use in roofs or skylight ventilators. Especially in those constructions where the transparent covering is inclined over an aperture in the roof of a` building. it is particularly desirable that when these transparent units are closed they be absolutely weatherproof. Accordingly, I have provided in each series a plurality of overlapping windows which are pivoted at the middle of each side portion in vertical or vertically inclined beams andl are so disposed that when they are closed the forward end of one window is provided with a depending flange which overlaps the corresponding forwardly extending fiange on the window immediately below in the" series.

To make the lateral edges of the window Vtight where they lie and pivot adjacent the edges of the supporting beams, I provide one end of each lateral edge of the window with an overlapping, channellike flange portion adapted to overlap an upstanding edge of the stationary beam, and on the edge lof the beam adjacent the rear portion 'of the lateral edge of the window, I provide ya stalvtiona'ry overlapping channel flange portionv adapted to receive the rear portionof the lateral edge of the window when the'window is closed. Particularly along the adjacent ends of these channel fiange portions they are curved and circular in form, the flange portions on the window slipping within the fiange portions onthe beam and having a common center coincident with the artis of the supporting shaft for the window. The forward portion of the channel flange member on the window is adapted, when the window is closed, to overlap the upper rear edge of the correspondingv flange portion on the beam immediately below the end of this window, so that the whole unit when closed is weatherproof.

Each unit is comprised as follows: A

frame, preferably made 0f sheet metal, designatedby the numeral l 'is adapted to receive transparent units 2. Each frame along its forward edge 3 is provided` with a depending flange portion 4 adapted to over-` lap, when in its closed position, an upwardly extending flange portion 5 on the rear upper end of the window immediately jbelow. Eachwindow frame is supported along my invention er@ adapted to be used in a lateral edges on bolts orA shafts 6 suitably 110 supported in T beams 7. This T beam is inverted, as shown in Figure 5, and the ends of shafts 6 are supported in plates 8 and 9. rlhese plates and the T beams 7 form part of a bar or stud which is preferably made of sheet metal 1() and provided with upstaiiding rib portions 11 along the upper lateral vedges to provide a channel along the upper face ofthe beam down which the water may flow.

Made integral with or suitably fastened thereto in any desired manner along the forward portion of each lateral edge of the frame 1 is an upturned, overlapping channel flange portion 12 which is adapted to extend over the adjacent rib 11 on the supporting beam. This channel flange portion 12 at its end adjacent the middle portion of each frame is formed circular in shape, as designated by the numeral 13, and is cut away in a suitable portion let so as to permit the window to have the required pivoted movement around the shaft 6. The rear of each lateral edge of the frame 1 is not provided with an overlapping flange portion, but in order to make this part of the window lframe weatherproof, the adjacent edge of the supporting beam is provided witha fixed stationary overlapping channel portion 15 which is adapted to ieceive the rear portion of each lateral edge of the frame 1 when the window is closed, as shown in Figure 2. The end of this general flange portion 15 adjacent the middle of the window section is curved circular in foiin, as designated by the numeral 17, and overlaps the above-mentioned curved flange portion 13 on the window frame. The angular eX- tension' of the curved flange portions 13 and 17 are so designed that they overlap each other sufliciently when the window frame is closed to prevent the water from getting through, vandseal the lateral edges of the window tight. rlhe upper rear end 18 of the channel portion 15 extends far enough up `on the edgeof the supporting beam to be overlapped by the front lower end of theV channel flange portion 1270i. the window .lient iii. order above in the series.

Any suitable operating means can be lisci! to actuate these windows separately or as" a unit, butpiefeiiably I use the actuating vineafiis which is the subject mattei' of my copendiiig application, Serial No. 3635111, skylight ventilator, filed March 5, 1920.

l It will thus be observed on consideration of the above description that l have provided a window construction whereby a plurality of window frames can'be pivotally V unit and which when in closed position premounted between beams and operated as a.

sent an absolutely weatherproof barrier between the elements and the interior. The various parts of this construction can be made of any suitable material, but is preferably l made of sheet metal; and minor modifications can be made in this structure without `departing from the spirit of the invention.

W'hat I claim is:

.1. window construction comprising a window framehaving lateral edges, a supporting beam on which the window frame is pivoted having an edge adjacent the lateral edge of the window frame, the edges of the beam rising above the top surface thereof to form a channel, a flange on the forward lateral edge of the window adaptedto overlap the adjacent edge of the beam, and a flange on the edge of the beam adapted to overlap the rear portion of the lateral edge of the window. l

2. A window construction comprising a supporting beam, a window frame pivoted thereto, a plurality of flanges disposed on the Vadjacent edges of the beam and the .window frame adapted to overlap each other to render the structure weatherproof when the window is closed, and a depending flange on the forward lower edge of the window frame adapted to overlap the edge of *theY adjacent Window. y

3. A window construction comprising a supporting beam, a window frame pivoted thereto, said window frame havinglaterah.

front and rear edges, a channel 'flange on the forward portion of each lateral edge Y adapted to overlap an edge of the beam, a channel flange on the edge ofthe beam adapted to overlap the rear portion'of the lateral edge of the frame, anda depending flange on the forward edge of the frame* adapted to overlap the rear edge of an adjacent window when the window yis closed. 4. A window construction comprising a supporting beam, a window frame pivoted thereto, a channel flange on the lateral edge of the frame adapted to overlap an edge of the beam, and a `channel flange on the edge ofthe beam adapted to overlap the lateral edge of the window frame, the adjacent portions of these flanges being curved in form, the curved portion of the flange on the beam adapted to overlap and jembiacc the curved portion of the flaiigeron the frame.

5. A. window construction comprising a supporting beam, a window frame pivoted thereto, a channel flange on the lateral eege of the frame adapted to overlap an edge' of the beam, and a channel flange on the edge of the beam adapted to overlap the in form, the curved portion of the flange Y on the beam adapted to overlap and embrace the curved portion yof the flangeV on the frame, the pivot point of the window frame being the center of each of said curved channel flange portions.
